Treated badly

I have an account with Nedbank for over 12 years. I use my account mainly for savings. I did not transfer money into my account and now my account is on hold for dormancy. So I call the call centre and get told I need to go into the Branch to uplift. So I go in into the branch, and I have never in all my life while banking been treated like a ******** on my now account just because I have a positive balance. I get the run around stared at, questioned, and account still on hold. I leave the branch so disappointed and call the call centre and get told just transfer R50 into the account and call today we will uplift. So I do that and guess what, when I call today I get told to go back to the branch. Please can yo inform me why I got treated so badly, how can a bank treat it customers like this. I want the hold uplifted so I can transfer my money another bank. I will no longer bank here this is tooo awful. I have no idea what has happened to Nedbank since I opened my account. Every person I speak to gives me another story about how to uplift the hold, I think I have spoken to about 9 people and each one tells me something else. Please train staff on the products.
